This video shows BYD’s 20 kWh lithium iron phosphate battery pack, based on BYDs own production cells. BYD calls this battery a ferrous battery, based on the chemical nomenclature for iron – FE. The battery pack runs down the center console, and has a lifetime of 2,000 cycles. To recharge the battery to 100% capacity using a household 220 VAC takes about 9 hours.

The battery resembles the battery being produced by A123 battery. General Motors didn’t choose the American made A123 battery group as their partner, instead they choose Korea’s LG Chem.
